CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 481,852, dated August30, 1892.

Applioationfiled April 22,1892. SerialNo.430,Z34. (No model.)

To aZZ whom it may concern:

Be it known that I, HARVY H. DOUGHERTY, a citizen of the United States,residing at WVaverly, in the county of Morgan and State of Illinois,have invented new and useful Improvements in Corn-Planters, of which thefollowing is a specification.

My invention relates to corn-planters, and has for its object to providenovel, simple, and

I0 efficient mechanism for operating the corndropping devices and toregulate or control the dropping of the corn so that it will be plantedin uniform rows.

To these ends my invention consists in the novel construction,combination, and arrangement of parts hereinafter described and claimed,reference being made to the accompanying drawings, in which Figure 1 isperspective view of acorn-planter 2o embodying myin vention. Fig. 2 isatop plan View. Fig. 3 is a front view. Fig. 4 is apartial side Viewshowing the indicating-wheel and pointer.

In the said drawings the reference-numeral 1 designates the runners,connected at their front ends by a bar 2 and carrying at their rear endsthe corn-boxes 3. Near their rear ends these runners 1 are firmlyconnected toget-her and braced bya cross-beam 4, to which is suitablyhinged or pivoted the groundwheel frame 5 in such manner that therunners 1 and ground-wheel frame 5 have a free vertical movement withrelation to each other to facilitate running over inequalities of the 5ground. These parts are of ordinary and Well-known construction and neednot be f urther described. I

Journaled on the axle 6 in the frame 5 are the ground or drive wheels 7,the hub 8 of one of which Wheels is extended outward sufficiently toclear the sides of the runners 1 and the corn-boxes 3, and suitablysecured to said hub is a cog, sprocket, or other chain-engaging wheel 9.

Secured, preferably, to the forward ends of the corn-boxes 3 arebrackets 10, in which is journaled a shaft 11, turning loosely, upon oneend of which is a suitable cog, sprocket, or other chain-engaging wheel12, extending 5o inwardly from the face of which is a lateral tooth orpin. I have shown and prefer to use only one tooth or pin; but obviouslya greater number could be used.

Secured to the shaft 11, adjacent to the wheel 12, movable into and outof engagement with the tooth 13, isa cog-wheel 14, havinga lateralgrooved extension 15, which is engaged by a forked arm 16, dependingfrom a lever 17, pivoted to across-bar 18, supported by the brackets 10.

The numeral 19 indicates the corn-dropping slide, which works throughthe corn-boxes in the ordinary manner, dropping the corn on oppositesides of the machine, and extending upwardly therefrom is a forked armwhich engages the horizontal member of a crankarm 20, which may, ifdesired, be provided with a cushion-washer, as shown.

The vertical member of the crank-arm 20 is secured to a small horizontalshaft 21, jour- 7o naled in the cross-bar 18 and carrying at its frontend a bevel gear-wheel 22. Secured to the shaft '11, intermediateitslength, are mutilated gear-wheels 23 and 24, each having, preferably,three teeth. These gear-wheels are so disposed upon the shaft 11 thatthe teeth of one wheel engage the gear-wheel 22 after the teeth of theother wheel have passed out of engagement therewith, whereby the bevelgear-wheel 22 is alternately rotated in opposite directions, thusimparting a reciprocating movement to the corn-dropping slide 19. Asprocket or other suitable chain 25 is trained over the wheels 9 and 12,imparting motion from the wheel 9 for-operating the corn-drop- 8 pingmechanism when the cog-wheel let is in engagement with the lateral tooth13 on the wheel 12. When the lever 17 is moved in the proper direction,the cog-wheel moves away from the wheel 12, taking the corn-dropping 9omechanism out of operation.

The distance between the different hills or place where the corn isdeposited is regulated by the relative size -of the chain-engagingwheels 9 and 12, a wheel 12 of small diameter 5 being used to impart arapid reciprocation to the corn-dropping slide 19 when the hills are tobe close together, and a wheel 12 of relatively-larger diameter toimpart a slower reciprocation to the corn-dropping slide, accord- 10oing to the distance apart at which it is desired to have the hills. Forinstance, if it be de sired to have the corn drop, say, three feet nineinches apart, a six-inch wheel 9 and a sixinch wheel 12 would beemployed, whereas to have the distance between the hills three feet sixinches apart a six-inch wheel 9 and a fiveinch wheel 12 would beadopted.

In order that the first hill in the field and the first hill in eachsuccessive row may be made at the required spot, I provide the followingmeans: Upon the shaft 11 at the end opposite the chain engaging wheel 12is mounted an indicator-wheel 26, upon the face of which are two scales,the first beginning with zero at the top and extending half-way roundthe periphery of the wheel and the second beginning with zero at thebase of the wheel and continuing around the periphery to the top. Asuitable metallic or other pointer 27 is secured to the frame of themachine adjacent to the wheel 26, the end of which points to the scaleson the face of said wheel. To the cross-piece 2, which connects thefront ends of the runners 1, are secured pointer-rods 28, which extendoutwardly from said cross-bar for a suitable distance and are then bentat right angles and extended back parallel with the sides of themachine. The parallel arms of said rods 28 are provided with a series ofholes or perforations adapted to receive loosely the depending pin 29.The 1111- meral 30 indicates a lay-out wire, which is constructed asshown in the drawings. The indicator-wheel 26 is so arranged on theshaft 11 that when the pointer is directed at zero on the scale on saidwheel the corn-dropping slide is ready to commence its movements, sothat if it is desired to have the corn-hills three feet nine inchesapart and the pointer indicates zero the operator will know thatthemachine will travel three feet nine inches before the first corn isdropped.

The organization and operation of the machine for a three-foot-six-inchdrop are as follows: A five-inch wheel 12 is placed upon the shaft 11and is engaged with the wheel 9 by the chain 25. The cog-wheel 14 beingout of engagement with the chain-engaging wheel 12, the indicator-wheelis turned until the pointer is directed at zero. The pin 29 is theninserted in one of the perforations of the pointer-rods 28 at a distanceof twenty-one inches from the corn-shoe. The lay-out rod 30 is thenplaced at a distance of twenty-one inches in front of the corn-shoe orat the point where it will contact with the pin 29. The machine is thenready for operation and will travel the necessary distance beforedropping the cornviz.,twenty-one inches in front of the lay-out rod 30.The cog-Wheel 14: is then thrown into engagement with the lateral toothof the wheel 12 and the machine is moved over the field the desiredlength of the row, the corn-slide dropping corn at each side of themachine. \Vhen the end of the row is reached, the corn droppingmechanism is thrown out. of operation and the lay-out rod is placed inthe position indicated by the pin 29, depending from the pointer-rod 28,which would be twenty inches beyond the point where the last bill wasdeposited. The machine is now turned around and moved to the positionwhere the pointer-rods engage the lay-out rod and the indicator-wheel 1sturned until the pointer is directed at zero. The machine is now readyto' plant the second row. Vhen the end of the second row is reached, thedriver will be apprised of the fact by the pendent pin on thepointer-rod coming 1n contact with the previously-laid lay-out rod.

By my invention it is possible to plant the corn more accurately than isdone by machines heretofore in use, and the distance between the hillsof corn can be easily and accurately regulated.

My improved attachment may be applied to use with almost everydiscription of cornplanter now in use.
